Help attaching clips

right, ive started to make an RPG game about an hospital. Ive only just started but i have a problem.
When the game enters the battle frame, i can’t get it to load a movieclip

And i put a code on it so it swaps depths with the y position it is at, but since ive done this it keeps makin multiple versions of it when i go to other frames

anyone help or try fix this please?

thanks
